A type of camera, usually expensive, meaning Single Lens Reflex. It usually has a pentaprism for a mirror setup, and reflects exactly what you will see in the picture to the eyepiece, unlike cheaper cameras that do not do this. cheaper cameras usally havea little hole that goes through the camera across from the eyepiece that you look though.

In EQ2 {Everquest 2} gear becomes bound to you when you do {loot it from a chest, in} an instance. You’re able to trade that loot with anyone who was in the instance for 48 hours after it was looted. What players do is leave the item in the chest, change the loot options to leader only (thus allowing you to assign the loot to someone) auction the gear in a channel, invite the winner to the group, summon them to the dungeon, and pass them the loot.
